Time difference correction mechanism and timepiece with time difference correction mechanism

A time difference correction mechanism comprising:

• a cylinder index star wheel that comprises teeth on an outer circumference thereof and is configured to connect to an hour hand;
• a cylinder index gear that comprises a bearing hole within a body of the cylinder index gear and teeth on an outer circumference of the cylinder index gear and is configured to connect to a minute hand, the cylinder index gear provided radially outward of the cylinder index star wheel and disposed on a same plane as the teeth of the cylinder index star wheel and coaxially with the cylinder index star wheel;
• and
• a cylinder index lever that is disposed in the cylinder index gear and on a same plane as the cylinder index gear,
• wherein the cylinder index lever comprises a lever portion and a spring portion integrally formed with each other, wherein the lever portion comprises a first end with a claw and a second end opposite the first end with a rotation supported portion configured to be received by the bearing hole;
• wherein the spring portion comprises a first end integral with the claw of the lever portion and a second end opposite the first end with a spring sliding portion placed relative to an inner edge of a recess in the cylinder index gear,
• wherein the cylinder index lever is configured to be rotatable about its axis between an engaged position where the claw of the lever portion engages with at least one of the teeth of the cylinder index star wheel and a disengaged position where the claw disengages with the at least one of the teeth of the cylinder index star wheel,
• wherein the spring portion is configured to bias the lever portion to the engaged position, and
• wherein a change of a position of the cylinder index lever in a direction of the axis is restricted by support portions that sandwich the cylinder index lever in the direction of the axis.
